A method is disclosed for producing branched aliphatic ketones in hydrocarbon mixtures from isoalkanes by a superacid catalyzed formylation-rearrangement reaction. The method can be used to simultaneously isomerize, if necessary, and formylate hydrocarbons in complex hydrocarbon mixtures such as refinery streams, alkylate mixtures, and natural gas liquids. Natural gas liquids of low octane number are upgraded and oxygenated by adding to the natural gas liquids or reactively producing in the liquids branched aliphatic ketones.
